Roebling Aqueduct

In a quiet and
often overlooked corner of Northeastern Pennsylvania, the country's oldest
surviving suspension bridge crosses the Delaware River into New York.
The Delaware Aqueduct, designed and built by famed engineer John A. Roebling,
has withstood a very colorful history from being an important piece in
the region's transportation, to uncertainty during the growth of rail,
nearly eight decades of neglect and poor management as a private toll bridge,
to finally being restored by the National Park Service and in use as an
automobile bridge today.

Construction and
Canal Era (1847-1898):During the 1840's, the Delaware &
Hudson Canal was looking at ways to speed up service along its route.
One of the major bottlenecks was where the canal reached the Delaware River.
Since it began operation in 1828, the D&H used a rope ferry to pull
traffic along to Canal across the Delaware. The conflicting traffic
of vessels going down the Delaware to Trenton or Philadelphia and of the
coal freight cutting across the river on the canal created great bottlenecks.
That is in addition to the difficulty ferry operators would have fighting
the powerful current. In 1847, the D&H commissioned
John A. Roebling to construct a suspension bridge that would carry canal
traffic above the Delaware. In comparison to then-contemporary designs,
Roebling's suspension design allowed for more room for downriver traffic
and the dangerous ice floes to pass through. Two years later
on April 26, 1849 at a cost of $41,750, Roebling's Delaware Aqueduct
opened to canal traffic. Soon thereafter, a sister suspension aqueduct,
the Lackawaxen, was opened nearby at a cost of $18,650. (1) The two
bridges' impact were immediate and impressive as canal traffic was shortened
by one full day. The D&H was so impressed by the success and
the bottom-line impact of the two bridges that they commissioned Roebling
to design and construct another two. Two years later, Roebling finished
the construction of the Neversink and High Falls Aqueducts in New York.

Eight Decades of
Neglect (1901-1980):As railroads grew throughout the
country, the need for canal traffic drastically declined. In 1898,
the D&H ceased operations. Three of the four aqueducts, Neversink,
High Falls, and Lackawaxen, were dismantled. The Delaware, which
still had a great deal of practical purpose as it crossed a major river,
was sold to a private owner. The owner, Charles Spurks, used the
now dry aqueduct to haul logs for his lumber company across the bridge.
He built a toll house on the New York side of the river charging a toll
to all others on the crossing. The bridge would change hands several
times during the next 70-plus years. As ownership changed, the condition
of the bridge deteriorated. The towpaths were dismantled, replaced
by a handrail. In 1933, the trunk of the bridge burned away completely.
Only the bridge deck was replaced, the walls of the aqueduct were not replaced.
A near tragedy occurred in 1977, when a truck fell through the bridge.
A lawsuit was filed against the then owners, but the bridge was only closed
temporarily. The condition of the bridge deck was so bad that one
member of the park service said, "All one had to do was hop up and down
on one end, and I could see a ripple running all the way from Pennsylvania
to New York." (2) In 1980, the National Park Service bought the bridge
and closed the structure in the hope to restore it.

Restoration and
Revival (1980-present):Once the National Park Service owned
the aqueduct, discussions and planning began on how to restore the bridge.
Before the bridge was under the Park Service control, the bridge was deemed
in 1968 to be a National Historic Landmark. In 1983, testing began
on the strength of the bridge, and amazingly Roebling's original provisions
easily met modern standards. With most of the original superstructure
intact, restoration began in 1985. The restoration of the superstructure's
base to Roebling's original specification was complete in 1986. In
1995, the aqueduct walls, towpaths, and wooden icebreakers at the base
of the piers were completed.Today, the bridge is again open to
vehicular traffic, without tolls. It is a one lane bridge, and the
former towpaths serve as sidewalks. The toll house on the New York
side remains and now serves as a history center detailing the history of
the aqueduct, the D&H Canal, along with the restoration process.
With all original features of the bridge restored, crossing the bridge
is like going back in time; the only difference, you don't need a boat
to cross it.

This sleepy little rural
town in Central Virginia can easily be overlooked. Located miles
from the Interstate or four lane US and Virginia Highways, Charlotte Court
House in many ways is easily forgotten. However, this tiny town of
slightly over 400 residents holds a lot of Virginia and American History.

In 1799, Charlotte Court House saw the passing
of the torch from an aging Patrick Henry and a young John Randolph.
The great debate over states' rights was the last for the fiery Henry and
the first in public for Randolph. Randolph would go on to serve in
the US House of Representatives and U.S. Minister to Russia. Henry,
who was serving in the Virginia General Assembly representing Charlotte
County at the time of the debate, died three months later.

Charlotte Court House is not the original name
of the town. Originally named The Magazine, then Daltonsburgh, followed
by Marysville (which was the town's name at the time of the Henry-Randolph
debate), Smithfield, and finally…

While researching the history of the Lanes Bridge crossing of the San Joaquin River I noticed an oddity on the 1935 California Division of Highways map of Madera County. Today California State Route 41 takes a crossing of the Fresno River west of the confluence with China Creek. Back on the 1935 Map of Madera County the crossing is very clearly east of the confluence crossing on what are now Road 425B and Road 426 in Oakhurst. CA 41 can be seen traversing southbound from Oakhurst on Road 425B towards Coarsegold on the 1935 Madera County Map.

After viewing Road 425B on the Google Street Vehicle it was clear that the path downhill from the top of Deadwood Gulch was substantially more haggard than the modern alignment of CA 41. I finally had occasion to visit Oakhurst today so I pulled off of modern CA 41 at Road 425B. Immediately I was greeted by this warning sign.

Road 425B ahead was clearly a narrow road but barely wide enough for two vehicles. T…

After leaving Barstow via Old Highway 58 my next destination was in Death Valley. To access Death Valley from rural San Bernardino County required a trek on north on Interstate 15 to California State Route 127 which becomes Nevada State Route 373 at the state line.

Along I-15 I encountered the road sign oddity that is Zzyzx Road about eight miles south of Baker. Zzyzx Road is a four mile road that used to go to the Zzyzx Mineral Springs and Health Spa. The spa was founded in the 1940s and the owner made up the name "Zzyzx" to claim it was the last word in the English Language. The spa has been shut down since the 1970s and is now part of a Desert Studies Center for California State University.

The southern terminus of CA 127 in Baker is located at I-15 exit 246. CA 127 is a 91 mile north/south highway which runs to the Nevada State Line in Inyo County. CA 127 is called Death Valley Road from I-15 northward. South of CA 127 the road continues as Kelbaker Road which c…
